Cleaning Your Pack
You are best to clean your pack with a natural, non-detergent soap and a soft-bristled brush. Suitable soap types are: pure soap, vegetable soap and Nikwax Tech Wash. Rinse the pack well and dry it in a well-ventilated area out of direct sunlight.
Do not put your pack in the washing machine as this will void your warranty.
The manufacturer of our zips, YKK, intentionally makes the zip slider from a soft alloy. This is so the slider (which is relatively easy to replace) wears out before the zip teeth (which are very difficult to replace). So, when zips are used extensively and in dusty or dirty environments the inner parts of the slider are worn away to a point where they cannot bring the teeth of the zip together effectively.
To get the worn sliders working until they can be replaced you can use a pair of pliers to gently squeeze the sides of the slider together. This should allow the slider to bring the zip teeth together. Don't use too much force because you can jam the slider.
Always try to keep the zip teeth as clean as possible. Wash them with fresh, clean water and lubricate with a silicon lubricant suitable for use on fabrics. This stops the dirt and dust from wearing away the insides of the sliders.
Find your Macpac Back Length
Locate your C7 cervical vertebra. Working down your neck, it's the highest vertebra that you can feel protruding near the base of your neck. No need to press hard, you should feel it easily through your skin. This point is usually a bit higher than your shoulders.
Its easier if someone helps you with this step. Measure vertically from your C7 to the floor in cm. Alternatively, mark the height off accurately against a wall or door frame with a piece of removable tape.
Find your Iliac crest. That's the highest point of the top of you hip bone at the side. Make sure you are not taking the front of your hip bone.
Measure vertically from your Iliac crest to the floor in cm. Alternatively, mark the height off accurately against a wall or door frame with a piece of removable tape.
Work out the difference between the two heights in cm. This is your Macpac back length. It is typically between 32 and 44cm for women, and between 37 and 49cm for men.
Men and women are different in body form and how they distribute and carry a load. Macpac have a number of women's models in our Liberator™, Liberator™ Freeload™, AirFlo™, Quantum™, Dynamic™, Wraptor™ and Active™ harnesses that offer optimal fit, comfort and performance.Design features
Shoulder straps are closer together so they sit on a woman's narrow shoulders and don't slip off.
Hipbelt is longer and more flared to fit over a woman's broad and curved hipbones.
Soft dual-density foam on the shoulder pads provides comfort across the sensitive chest area.
Lower-profile shoulder pads with tapered thickness under the arms provides more clearance and reduces chafing.
Sternum strap is narrower and sits higher.
Small and less bulky buckles are used to get a neater fit on a woman's smaller frame. This also makes them easy to adjust and open with small hands. Note: Features vary depending on the load-carrying system
I have one of these since 2012 and have used it almost everyday for work and travel between 2012 to 2015. Except for one of the zip cord that has snapped (easily solved by tying another cord to the zip) the pack is still gg on strong. Packs an amazing load of things despite its small size. Fits comfortably. Highly recommended.
